This will be the start of a very inexpensive project truck that most enthusiasts can do in their own garage. And to prove it, we're putting away our fancy cold saws and tube benders, and will create our own two car garage inside our Xtreme shop with minimal tools but with all the drive and desire you guys have at home for your projects!

Jeep Scrambler gets its tub, drivetrain, beadlocks and more all in a 2 car garage with simple tools.

And on the CORR track, no one has made more trips to the podium in the last 10 years than Carl Renezeder. This champion Pro 4 driver with his rig and team are profiled.

The Bottom Drawer Buggy gets new axles when dual Rockwells are shaved, reduction housings modified, and pinion brakes are installed. Then this budget tube buggy is taken out for one of our most hardcore payoffs ever!

Ian and Jessi and the crew travel to West Sacramento, California to a trade school where top students in chassis fabrication get the opportunity of a life time: build a competition rock crawler on TV from scratch! See how 21 apprentices band together with the Xtreme 4x4 to build a Formula Toy competition rig they can be really proud of!

Ian and Jessi head back to West Sacramento where their Formula Toy rock crawler has been sitting in the lobby of the trade school since their last visit. This time 10 more students join them to plumb, wire, and fire this trick buggy. In the end, there's a special bonus for this team of student-builders, when they get to participate in the Xtreme challenge. On a course set up by W.E.ROCK, they team up to see who is champion of the rocks!

The desert bandit makes a return to the shop for interior finishing, dash, gauges, wiring and the suspension... all will come together today. Plus, a trip down to South Florida for their legendary swamp buggy races!

It's been a year and a half in the making and today, their ultimate 4x4 Ranger will hit the dirt, after Ian and Jessi plumb and fire the motor. Plus... we head to the Southern California race shop of legendary Off Road Champion Ivan "Ironman" Stewart, where we get a tour and learn the secrets to his 84 career victories!

An old worn out Land Cruiser gets new life as Ian and Jessi begin project Saggin' Wagon. The project starts with new suspension. And in our event of the week, Ian and Jessi travel to Pomona, California and the Off-Road Expo "a Shangri-La" for off-road enthusiasts. Ian and Jessi pick two unsuspecting guys out of the crowd who drive very different rigs. Both think they're going window shopping, getting ideas and suggestions with the help of our hosts. When in reality, we are helping them build their rigs - in the end, they find out all the parts are FREE!

Ian and Jessi grab the reciprocating saw and plasma cutter and back half their beat up Toyota FJ60. This trail runner project will get new lockers, axles, and a four link suspension. Plus we'll travel to Columbus, Ohio for the W.E.ROCK Nationals and a look at professional rock crawling through the eyes of the judges!

The Toyota FJ60 returns to have the front roll cage constructed as well as adding fuel injection to the motor, plus exhaust, lights, and all the wiring. Then co-host Jessi Combs takes us to the South Dakota Territory Challenge outside Rapid City, where 200 rigs from all over the country come to run the "xtremely" challenging Black Hills.

What is old is new again, when Ian and Jessi make a true trail truck out of the new Toyota FJ with 6 coil overs, beadlocks, lockers and more. Then their back-halved Saggin' Wagon Land Cruiser is finished off. Plus, 3 hours non-stop through the woods, rivers, jumps are what Casey Illinois endurance racing is all about! Even the eventual winner breaks down before the finish line!

Two decades apart, and vastly different our '85 Landcruiser and '07 FJ Cruiser are readied for the trail. See how full air lockers and an off road lift improves Toyota's new FJ in the field in this hardcore payoff. And in our event of the week - they don't call it Axle Alley for nothing. We're off to the Arizona desert and one of the West's most bone crushing trails.

One of our more popular builds makes a return, this time for a junkyard transmission build and beefier transfer case. Our budget CJ7 will be a better performer on the rocks after this show. Jessi has honors on the Dana 300, while Professor Johnson debunks the myth of the automatic transmission, by tearing it down and rebuilding it right before your eyes!

To manual shift, or not to manual shift? That has been the question on the legitimacy of pulling the manual transmission out of the Cheap Jeep in favor of a rebuild junk yard automatic and transfer case.

Xtreme's most popular build to date - the Cheap Jeep (1982 Jeep CJ) returns. And the last remaining weak link is upgraded in the form of beefier and stronger off-road axles. Plus, axle tech - everything you wanted to know about axles will be discussed in this show. And in our event of the week, some top off-road shop teams compete in a Midwest challenge to determine the best of the best in this two part "Top Shop Challenge"!

One of our favorite budget projects returns for beefier axles. See how a Ford 9" and a Dana 44 turn a competent crawler into a trail monster! Plus, there's more to a Truck Fest than just monster trucks and bikini contests! Watch our crew give away almost $10,000 of free stuff at the inaugural 4 Wheel Parts - 4 Wheel Drive Hardware Truck and Jeep Fest in Canfield, OH!
